PROBLEM is severe Diarrhea
Have 2 good days and 4- to 5 bad days losing 10 or more lbs

Can anyone advise how to stop the Diarrhea?

I’ve be plagued with daily diarrhea for several years. Lost some weight, not as much as you. Never knew when it would hit. Can’t ever make plans for my mornings. Like you, out of 7 days, I would have diarrhea 5 days, sometimes up to 10 times/day. Went to the Dr. He wanted to run the same tests I had 2 years ago. All came back normal except the bills! I did my own doctoring instead. Went lactose free a couple of yrs. ago. Started glutton free. There was some improvement, but not totally. Last month, I pulled out my back for the first time in my life. I took some opioids to get me to sleep at night. Usually, one pill always constipated me & I’d stop. Instead, it stopped my diarrhea! A miracle! I feel so much better. I know I can’t stay on the pain meds forever, but I’m just sharing with you what worked for me. Wish you the best. I know what you’re going thru.
